FIELD: radio engineering, communication.SUBSTANCE: methods and apparatus for communicating and utilising persistent allocation of resources are described. A base station can allocate persistent resources to a client station and can associate the client station or persistent resource allocation with a particular shared NACK channel. The base station can monitor the NACK channel for a NACK indicating a map error. The base station can also monitor the resource allocation to implicitly determine a map error. The base station can resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation can monitor persistent resource allocation information elements in map messages and can indicate failure to receive a persistent resource allocation information element in a NACK message on a preassigned shared NACK channel.EFFECT: high flexibility of resource allocation.14 cl, 10 dwg |
